Renesola 425Watt Saturn Series Bifacial-All Black Frame and Back Sheet

Half Cut Cells for better energy production under the shadow

Reliable Quality and Outstanding performance - TOPCon

We offer a 25-year warranty on performance, which means we are sure about our products will generate at least 80% of the nominal power after 25 years. All our panels have positive power tolerance from 0 to 3%.  

Incidence Angle Modifier (IAM) is very low, meaning the amount of loss due to the reflection of the solar rays on the glass. Renesola panels have exceptional IAM factor due to the meagre amount of power loss in the glass. 

Even in weak daylight, the panels will still produce an adequate amount of energy. On cloudy days still 20-30% of power is still available.

Advantages of Half-Cut Cell Solar Panels

  • ​​​​​​12-year product warranty and 30-year warranty of efficiency, 87.5% after 30 years
  • Total black look for particular architectural requirements
  • 9 busbar 182x182mm half-cut TOPCon cells
  • High module efficiency up to 22%
  • More Reflected light to the cell thanks to the round ribbon
  • 2 independent section design secures a higher energy yield in case of shading
  • Lower risk of hot spots and micro-cracks
  • Improved low-light performance
  • Low NMOT, improving the power generation efficiency
  • Half-cut design in combination with multi-busbar reduces operating current and internal resistance
  • Safe investment for your home and business. Performance is secured for 25 years.

What is TOPCon Technology  (tunnel oxide passivated contact)?

TOPCon applies an additional tunnelling oxide passivation layer to the solar cells. This technology offers an unbeatable combination of efficiency and reliability relative to capital cost. PERC Cells (passivated emitter rear contact) become more powerful and efficient with the TOPCon process.

The product is certified according to the IEC international standards:

  • IEC 61215(2016),IEC 61730(2016) ISO9001:
  • 2015:Quality Management System ISO14001:
  • 2015:Environment Management System
  • ISO45001:2018:Occupational Health
  • and Safety Management System

Lower losses in electric wires

Half-cut cells produce the same voltage as full-size cells, but the current passing through is half. As a result, the losses in the wires are reduced.
